LP8864QRHBRQ1 Description

Short technical summary and product information.

The Texas Instruments LP8864QRHBRQ1 is a high-efficiency automotive LED driver designed for display backlighting applications. It features four high-precision current sinks, each capable of delivering up to 200mA DC current. The device supports a wide input voltage range from 3V to 48V and offers flexible dimming control through Analog, I²C, or PWM interfaces.

 

This LED driver incorporates a boost or SEPIC DC/DC controller with an adjustable switching frequency ranging from 100kHz to 2.2MHz, allowing for optimization to avoid AM radio band interference and reduce EMI. It provides extensive fault diagnostics for reliable operation. The LP8864-Q1 is AEC-Q100 qualified for automotive applications, making it suitable for demanding environments.

 

The device is available in a 32-VQFN (5x5mm) package and is designed for surface mount, wettable flank mounting. Its applications include backlighting for automotive infotainment systems, instrument clusters, smart mirrors, and heads-up displays.
